Patented May 10, 1932 UNETED STATES PATENT OFFICE ARTHUR L. KLINE, FDETROIT, MICHIGAN, ASSIGNOR, BY MESNE ASSIGNMENTS, TO PACKARD MOTOR CARCOMPANY, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN PAINTINGINSTRUMENT Application filed March 22, 1928. Serial No. 263,625.

This invention relates to painting instruments and more particularly tostriping pencils.

Heretofore in the art of painting, and particularly in the art ofpainting vehicles, striping has been performed by hand and this methodhas been found not only slow and costly but altogether unsatisfactoryowing to the lack of uniformity due to the personal equation enteringinto the work and the absence of suitable means whereby the work mightbe accomplished with mathematical precision. To overcome theseobjections is the aim of the present invention.

An object of the invention is to provide astriping pencil for painting astripe on plain or curved surfaces.

Another object of the invention is to provide a striping pencil forpainting stripes of uniform width.

Another object of the invention is to provide a striping pencil forpainting stripes regardless of the plane in which the stripes may bepositioned, that is, regardless as to whether the stripes arehorizontal, vertical or inclined. V

A further object of the invention is to provide a striping pencil havingan automatic ejecting means operated by the movem-entof the pencil overthe surface to be striped.

A further object of the invention is to provide a striping pencil havinga chamber and an auxiliary chamber connected therewith and means in theauxiliary chamber for auto matically ejecting. fluid from the auxiliarychamber through a nozzle in a predetermined flow of uniform volume perunit area of work painted.

A further object of the invention is to provide a striping pencil havinga chamber and an auxiliary chamber connected therewith, the auxiliarychamber having a nozzle and means therein for ejecting fluid from theauxiliary chamber throughthenozzle, the

ejecting means being automatically operated by a rotatable guide for thepencil.

Other objects of the invention will appear from the followingdescription taken in connection with the accompanying drawings, whichform a part of the following specification, and in which:

Figure 1 is a top plan view,

Figure 2 is a side elevation, and

Figure 3 is a longitudinal sectional view.

Referring to the drawings for more specifi0 details of the invention, 10represents a chamber having formed integral and parallel therewith anauxiliary chamber 11. anxiliary chamber 11 has arranged thereupon a boss12, the object of which will hereinafter appear, and the chamber 10 hasthreaded in one end thereof a barrel 13 providing an extension of thechamber 11 and in the free end of this barrel is positioned a checkvalve comprising a plug 14 having a vent 15 normally closed by a springpressed ball 16. In the other end of the chamber 10 is a port 17 and acommunicating recess 18, and check valve controlling the port 17. I

As shown, this valve comprises a spring pressed ball 19 positioned inthe recess and a retaining plug 20; the ball normally closes the port 17and leading from the recess 18 is a passage 21 communicating with theauxiliary chamber 11. The auxiliary chamber 11 has threaded into one endthereof a plug 22 axially bored as indicated at 23 and threaded on theplug is a nozzle 24, the nozzle having arranged therein a valvecomprising a spring pressed ball 25 adapted to normally close the borein the plug.

The auxiliary chamber 11 has positioned therein for reciprocation aplunger 26 provided with a'rack 27 and an operating handle .28. The boss12 on the auxiliary chamber 11 is transversely bored to receive a shaft29 on which is keyed a pinion 30, the pinion being in mesh with the rack27 on the plunger 26 and keyed upon one end of the shaft 29 is The i aspiral gear 31, the object of which will hereinafter appear.

Supported for oscillation on the shaft 29 is an arm 32. This arm isyieldingly depressed by a spring actuated plunger 33 p sitioned in theboss 12 and made adjustable relative to the chambers by a set screw 34.

Mounted for rotation in the free end of the arm is a roller 35 andpositioned above the roller is a transverse bore having journaledtherein a shaft 36. The shaft 36 has keyed on one end a spool guide 37the face of which is covered with rubber or any suitable material whichwill prevent slipping and keyed upon the otherend of the shaft is a wormgear 38. A shaft 39 is supported in suitable brackets on the arm 32. rThis shaft is parallel to the arm 32 and keyed on one end thereof .is a

gear 40 in mesh with the worm gear 38 and mounted for rotation on theother end of this shaft is a spiral gear 41 in mesh with the spiral gear31 on the transverse shaft 29. The gear 41 carries one member 42 of aclutch,

the other member 43 of which is mounted for reciprocation on the shaft39 and is normally held in engagement with the member 42 bya spring 44.

In operation, liquid paint is placed in the chamber 10 and the barrel 13and the plug 14 is threaded in the end of the barrel. Upon withdrawingthe piston 26 by the handle 28 paint will be drawn from the chamber 10through the port 17 and the passage 21 into the auxiliary chamber 11.The suction created by pullingoutwardly on the piston 26 is sufficientto open the valves in the chamber 10 and the barrel 13 and these valvesare immediately'seated or closed upon discontinuii ance of the suctionor the outward movement of the piston 26.

When adjusting the instrument to the surface to be striped the nozzle iseither adjusted by the set screw 34, or pressed in position against theresistance of the arm 32.

Upon drawing the instrument over the surface tobestriped the guideroller '35 rotates the worm gear 38 which through the shaft 39, gear 40and spiral gear 41 drives the spiral gear 31 and hence the shaft 29carrying the pinion 30. The pinion 3O meshes with the rack 27 on thepiston 26 and moves the piston forward in the auxiliary chamber 11 toeject paint through the nozzle 24 against i the action of the springpressed ball 25. Durclutch is disengaged and the piston 26 is drawnoutwardly by the handle 28 Whereupon paint is again drawn from the mainsupply chamber 10 and the barrel 13 through the port 17 and passage 21to the auxiliary chamber 11 whereupon the clutch is thrown intoengagement for the next operation.

Although this invention has been described in connection with certainspecific embodiments, the principles involved are susceptible ofnumerous other applications that will readily occur to persons skilledin the art.

The invention is, therefore, to be limited only as indicated by thescope of the appended claims. 7
